Objectives
The objective of this course is to provide the students with scientific knowledge in the field of dynamics (kinematics + kinetics) whether applied to the material point or rigid body. In line with the theoretical background acquired in lectures, the students should be able to solve analytically a list of standardized problems collected from the literature and others proposed by the professors. According with the given fundamental methods to solve problems in dynamics the student should be able to derive the governing equations of motion. Furthermore, he must realize the advantages and drawbacks of each method. He should develop his ability to discern what method is efficient the most to be applied to a specific physical problem in dynamics since each method has its own specificity, applicability and degree of complexity.
Subject matter
The program covers kinematics and kinetics of particles and planar rigid bodies. One starts reviewing some basical concepts of physics and mathematics. Then one moves to kinematics followed by kinetics with applications to particles and then planar rigid bodies. In kinetics one introduces the three fundamental methods to solve problems in dynamics: 2nd Newton Law, Principle of work and energy, Principle of Impulse and Momentum. Finally, one addresses the problem of rotor or shaft balancing.

Teaching method
Theoretical lectures and practical classes are planned. At the lectures notes on the subject are provided in the blackboard and complemented by powerpoint slideshows (videos may be included). At the practical sessions the resolution of some standard problems is demonstrated at the blackboard and the students required to go along and afterwards they are asked to solve extra problems by their own.
Evaluation method
The evaluation can be carried out on a continuum basis across the semester by means of three theoretical/practical tests. In case the student fails this evaluation or decides to improve it there is always the option of a final examination. All students are admitted to this final exam.
The continuous evaluation comprises two Tests (T1 and T2) and one Mini-Test (MT) and the approval is based on the following formula:
0.40*T1 + 0.15*MT + 0.45*T2 >= 9.5 where T1,T2 and MT range from 1 to 20. T2 required with a minimum of 8 in 20.
T1 and T2 are scheduled for a specific date and time gathering all the students at the same time.
MT is carried out at the classroom during practical classes at each shift during the same week (to be selected from the calendar).
In case the student doesn''t succeed in the continuum evaluation the final approval depends on the final exam only ranging from 0 to 20.
